Frequently Asked Questions
Everything you need to know about Keyword Density Checker
What is keyword density?
Keyword density is the percentage of times a keyword appears in your text relative to the total word count. For example, if 'SEO' appears 5 times in a 200-word article, the keyword density is 2.5%. It's a key metric for on-page SEO optimization.
What's the ideal keyword density for SEO?
Most SEO experts recommend keeping primary keyword density between 1-3%. Below 1% may not be enough for search engines to understand your topic, while above 3% risks being flagged as keyword stuffing. Focus on natural, reader-friendly content.
What are n-grams?
N-grams are sequences of n consecutive words. 1-grams are single words, 2-grams (bigrams) are 2-word phrases like 'content marketing', and 3-grams (trigrams) are 3-word phrases like 'search engine optimization'. Analyzing different n-gram lengths reveals different keyword patterns.
What are stop words?
Stop words are common words that carry little meaning on their own, like 'the', 'is', 'and', 'a', 'to'. Filtering them out helps you focus on the meaningful keywords in your content rather than common function words.
Can I check a specific keyword?
Yes! Use the keyword search field to look up any specific word or phrase. The tool will instantly show its frequency and density percentage in your text.
What do the colors in the density table mean?
Green indicates low density (under 2%), yellow indicates moderate density (2-4%), and red indicates high density (over 4%). This color coding helps you quickly spot keywords that may be overused.
Is there a word limit?
No limits! The tool analyzes text of any length in your browser. It handles long articles, e-books, and entire documents without restrictions.
Can I export the analysis?
Yes! Click the 'Export CSV' button to download your keyword analysis as a CSV file. The export includes keyword, count, and density percentage for every entry.
